was being 'flip' with you, but upon rereading, no haven't done this. especially
where 'multiple' answers are possible.

I have four equations:
f1 (x1, x2, x3, x4, x1*x3, x1*x4, x2*x3, x2*x4)=0
f2 (x1, x2, x3, x4, x1*x3, x1*x4, x2*x3, x2*x4)=0
f3 (x1, x2, x3, x4, x1*x3, x1*x4, x2*x3, x2*x4)=0
f4 (x1, x2, x3, x4, x1*x3, x1*x4, x2*x3, x2*x4)=0
Is there any way of solving these four quadratic equations in octave?
